There are a couple of stumbling blocks for the whole 4rotor thing, one: what ecu will control eight injectors, and run split timing, and two: the only porting option is a P port since there are two intermetiate housing, both of which have only primary ports.
The Microtech LT16 will be available in the next few weeks. It has all the functions a 4rotor requires and is designed with n/a engines in mind e.g 32x32 instead of 16x16 and user definable load points.
The owner of the red FD is currently working on a sideport 4 rotor using tallport center plates. He's using a robot arm and flow bench to get all ports flowing the same amount.

Does it make a difference how the air flows, or is it just the volume that matters?

Well, both. You want the same port timing on each rotor. After you use a template for modifying port timing, you would want to flow test it to make sure each port is just as efficient as the others as far as volume goes.

I still have not heard back from my original email to Jeff (precision) which makes me wonder whether or not he thinks I'm serious or not. So I guess I will just have to email him till he gives me the time of day, or tells me to **** off

Sad when you have to pester someone to take your money.
Damn Skippy. I also dint think that I was as ready as I thought...still lots of things to consider about the project, just dont know whether or not it has anything to do with the parts that I need to get from Jeff. For example, I thought about the OPM and if it still needs to be used, or does it depend on the ioling system, or do I just want to run premix? Sometimes I wish there was just a cheat-sheet...

Call Jeff Bruce at Precision Engineering, NZ 09 4153264. He makes the shaft , modifies the side plates to take stat gears dowels and pp's the rotor housings. Kiwi re just gets the bits and adds there 150% markup.
I spoke to Jeff about a week ago , and there is a US agent that sells the stuff , but i forget who he said it was.
he have an email address?

I need your opinions on using a GSL-SE intermediate plate in the centor of a 4 rotor 12A. It's the only one with threaded holes at the bottom of each side for motor mounts, and is compatible with earlier rotor housings. I figured the engine's extra 128lbs of weight would be ok if centered over the motor mounts instead of hanging from the front cover and bellhousing. Thoughts?

Or what if I used two GSL-SE intermediate plates; each one with a stationary gear/bearing, with motor mounts spanning one to the other? I'd think the engine would be better supported. A regular 12A plate would be in the middle.
